MEANS FOR VARYING THE 'AREAL DELIVERY OF BOSE-HEADS.

To all whom it may concern:

Be it known that I, Gannon COLVIN KEN- NEDY, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements-in Means for Varying the Areal Delivery of Rose-Heads, of which the following is a specification.

My invention relates to improvements in means for varying the areal delivery of roseheads, and the object of my improvement is to combine with a sprinkling-device or the like, adjustable means adapted to both variably restrict the area of the delivery surface and permit thecontrolling of the direction of the rose-jetthereof.

This object I have accomplished by the meanswhich are hereinafter;described and claimed, and which are illustrated in the accon'ipanying drawings, in which:

figure 1 is a horizonta section of a rosehead, taken on the line 0-d of 3, with the division contrivance therefor shown in one position therein.

Fig. 2 is a like view of the rose-head, with the division-contrivance shown in another position.

Fig. 3 is a vertical central section of said rose-head and division eontrivance, taken on the line ab of said Fig. 1. V

Fig. 1 is a diminished plan view of said device, with parts broken away to disclose the division contrivance seated to restrict the discharge to one-half of'the area of the rose-head.

Fig. 5 is a like View of the device, showing the division contrivance set to restrict the discharge to one quarter of the 'ar'ea of the rose-head. I

Similar numeralsof reference denote corresponding parts throughout the 'several' views. r

The dome-shaped rose-head 6 has a large number of small delivery perforations .7 distributed evenly over it, and is interiorly threaded at its lower end to be secured removably and adjustably upona basal casting 1, the latter having a circumferential thread 4. a v

y The base 1 has an integral curved nipple 2, whose orificed end 3 has an interior 7 thread to removably receive a threaded. coupling on a hose 12, and the orifice 3 may open into any part of the rose-head 6, but is Specification of Letters Patent.

Application filed April 12, 1917. Serial No. 161,655.

shown eccentrically placed in order to permit of the central locating of the division contrivance.

An integral depending spike 5 may be provided on the lower face of the base 1 to fix the same to the ground, but this may be omitted when such a fastening-means is not desired.

The division contrivance is placed upon the upper face of said base 1, and comprises a diametral plate 9 whose upper edge is curved to conform to the inner wall of the rose-head and fit tightly thereagainst when the parts are clamped together. The plate 9 may have an angularly projecting part 9 to subdivide the interior space of the rose-head on that side. An interiorlythreaded socket 10 in the division contrivance 9 registers with an orifice 8 in the rose-head, and a thumb-screw 11 has its threaded spindle passed through the orifice 8 into the socket 10, and when rotated tightly clamps the upper edge of the parts9 to the rose-head preventing leakage therebetwcen. When the part 9 is renamed, the screw may remain to close the orifice 8.

The base 1, when screwed up, fits the bottom of the division contrivance to prevent leakage therebetween.

The division contrivance 9 may be mount ed in the rose-head 6 in the position shown in Fig.2 to cut off one-half of the spraying area, or reversed, as shown in Fig. 1, where the part 9 cuts off all but one-fourth of the spraying area, the base 1 being then screwed on, and the thumb-screw employed to clamp the parts together.

In Fig. 45, the division' oontrivance is shown in use to cut 0E one-half the spraying area of the rose-head at the edge of a walk or boundary line 13, so as not to cast any claim as new, and desire to secure by Letters Patent, is:

1. In combination, a rose-head in communication with a source of fluid supply, and a removable branching division contrivance therein.

2. In combination, a rose-head in com-' munication with a source of fluid supply, and a differentiating imperforate division contrivance changeable therein to variably cut off portions of the areal delivery surface thereof from said fluid supply.

3. I11 combination, a rose-head in communication with a source of fluid supply, and a removable division contrivance therein consisting of a unitary branched member adapted to vary the areal delivery surface of the rose-head when said divisicn contrivance is changed in position.

4. In combination, a rose-head in communication with a source of fluid supply, and a removable radiating division c011- trivance therein reversible in position to selectively cut off determined different sized portions of its delivery area from said source of supply.

5. In combination, a rose-head in communication with a source of fluid supply, a reversible differentiating division contrivance removably mounted therein, and means for fastening said division contrivance therein to prevent leakage between it andthe contacting parts of the rose-head. V

6. In combination, a rose-head, and an imperforate branched division contrivance therein adapted to be positioned to cut off varying areas of the delivery surface of the rose-head from the source of fluid supplythereto.

7. In combination, a rose-head having a removable base, and a division contrivance removably mounted between said rose-head and base and adapted to variably cut off portions of the delivery-area of the rosel1ead.

8. In combination, a r0sehead, a removable base therefor having an inlet-port, and a division contrivance mounted removably between said rose-head and base adapted to cut off a portion of. the-delivery area of the rose-head from said inlet-port.

copies of thii patent may he bbtained for 9. In combination, a rose-head, a remov able base therefor having an inlet-port and a branched division contrivance mounted be tween said parts, reversible to cut off varying portions of the delivery areav of therosehead from said inlet-port.

10. In combination, a rose-head, and imperforate recessed means mounted adjustably therein to cut off greater or less segable base therefor provided with an inletport, and a division contrivance seated removably and fittingly between the rose-head and said base, said contrivance consisting of a diametral partition for the rose-head having a lateralpart extending at a right angle from its middle at one side, said contrivance being reversible in the rose-head to cut off a one-half or a one-quarter segment ofthe delivery surface thereof from said inlet-port.

13. In combination, va dome-shaped rosehead, a closure therefor having an inlet-port and a removable partition fitted betwen said closure and rose-head, dividing the interspace into unequal compartments, of which one only at a time is in communication with the inlet-port.

1%. In combination, a rose-head ,provided withnumerous deliveryrorifices, a closure therefor, and a T-shaped division-contrivance mounted bet-wen the closure. and the rose-head.
